Algebra.Com's Answer #543945 by rothauserc(4718)![]() ![]() You can put this solution on YOUR website! 2x^2 = 7x-3 \n" ); document.write( "2x^2 -7x +3 = 0 \n" ); document.write( "the quadratic formula is x = (-b +or- square root (b^2 -4ac))/ 2a and standard form for quadratic is ax^2 +bx +c = 0 \n" ); document.write( "now we can solve our equation \n" ); document.write( "x = (7 + square root(7^2 -4*2*3))/(2*2) = 8.25 \n" ); document.write( "x = (7 - square root(7^2 -4*2*3))/(2*2) = 5.75 \n" ); document.write( "therefore x = 8.25 or 5.75 \n" ); document.write( " \n" ); document.write( " |
